Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To simplify the issuing work of a new ticket within the train by providing an optically inputting means for inputting ticket information in an exterior device on the surface of the ticket. SOLUTION: In the event where a conductor works to issue a new ticket within the train for the change of a destination or the like, since the same information as the content of a ticket 10 possessed by the passenger is indicated on an optically inputting means 12, the information can be inputted on an exterior device with ease by the use of the optically inputting means 12. Also, the optically inputting means 12 of the ticket 10 is a bar code, so that it can be inputted on the exterior device promptly correctly. Accordingly, information can readily be inputted even while being stood in the rocking train or operating the portable terminal by one hand.  In addition, inasmuch as a bar code is utilized in the optically inputting means 12, the ticket can strongly withstand against fouling, scratching, and so forth, e.g. even when the passenger can so fold the ticket accidentally that information on the rear of a magnetic information recorded layer can not read, inputting can be done from the optically inputting means 12.

Title: Optical cable and its manufacture
Inventor: KOYASU OSAMU
IPC: G02B6/44
Filed: 1995-09-15
Abstract: PROBLEM TO BE SOLVED: To facilitate post-branching and handling of an optical cable without using a waterproofing jelly in the manufacture. SOLUTION: In this manufacture of an optical cable that has a small number of coated-fibers and is used for meeting small scale demand, a spiral material 41 formed by spiraling a plastic tape is wound around bundled coated optical fibers 14 to form a loose tube 42. Then, a water-absorbing tape layer 44 is formed on the loose tube 42 to obtain an optical unit 46 and the optical unit 46 is covered with a sheath 20 to manufacture the objective optical cable 48. This water-absorbing tape layer 44 functions as a barrier to water passed through the sheath 20.  Also, when the spiral intervals (a) of the spiral material 42 are intentionally widened, a water-absorbing powder released from the water- absorbing tape layer 44 falls into the inner side of the tube 42 from the spaces formed in the spiral material 41 and the powder absorbs water and is swelled to restrict the permeation of water that penetrates into the tube 42, within some local areas. Since the diameter of the loose tube 42 depends on the size of the spiral material 41, the optical cables having various sizes can be manufactured by a single device.

Title: Rotary head type recording device
Inventor: TANAKA MITSUGI
IPC: G11B5/024
Filed: 1985-11-25
Abstract: PURPOSE:To erase only a desired part of each track without increasing the number of rotary erasing heads, by inclining and placing a direction of a head gap of the rotary erasing head, in the longitudinal direction of a tape-shaped recording medium from the direction vertical to the trace direction. CONSTITUTION:Recording is executed by using six pieces of recording heads on the periphery of a drum. Accordingly, when one piece of flying erasing head (FEH) has been used, six tracks of one field portion are erased simultaneously. Between a video are and an audio area, a guard space B is provided, but in order to execute a high density recording, the guard space is made as narrow as possible. Therefore, a gap of the FEH is inclined in the longitudinal direction of a tape from the direction vertical to the trace direction. In this way, even if width of a rotary erasing head becomes wide, the FEH can reduce the trace distance simultaneously against the width direction of a tape-shaped recording medium, therefore, only a desired part of each track can be erased.

Abstract: PURPOSE:To skew the deviation of the setting angle of an antenna with a signal from an indoor unit by adjusting a setting signal from an outside, and changing both-side voltages of a resistor. CONSTITUTION:The output voltages of arithmetic amplifiers 53 and 54 are respectively inputted to the plus terminals of following arithmetic amplifiers 55 and 56. Thus, the control voltages corresponding to the voltages supplied to non-inversion input terminals can be obtained at terminals 57 and 58. Also, the value of currents flowing through a polarizer 10B is decided by the value of resistance of a resistor 16, and the value of currents can be freely decided according to the kind of the polarizer 10B. Then, at the time of a fine adjustment, the voltage difference between the arithmetic amplifiers 53 and 54 is lineally changed corresponding to a pulse width, so that the voltage difference can be turned to the voltage difference between the terminals 57 and 58, and then the value of currents flowing through a coil 50 of the polarizer 10B can be varied.

Title: Multiimage forming device
Inventor: KAWANO YUZO
IPC: G03G15/16
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To make the constitution of a color slurring correcting means simple and inexpensive and to easily adjust a color slurring by providing a speed adjusting means for changing the respective moving speeds of image carriers. SOLUTION: A photoreceptor drum 1a is rotationally driven in the direction of an arrow C by a driving motor 13. When the rotational speed of the driving motor 13 is increased to make the circumferential speed of the drum 1a faster than the carrying speed of an intermediate transfer belt, a latent image line whose writing is started from a scanning start point D is moved up to a position for a scanning end F, to be formed as a latent image line (f) at an inclined angle smaller than that of a latent image line (e). In such a case, the circumferential speed of the drum 1a is changed to correct a deviation in an inclination, so that the inclination of a transfer line is varied to make the inclinations of the transfer lines of respective color images the same.  For instance, the circumferential speeds of other photoreceptor drums are independently changed to make the inclined angles of the transfer lines coincident with that of the drum 1a. In other words, adjustments are made to make the inclined angles coincident, to correct deviation values.

CONSTITUTION:A photoelectric sensor 18 outputs detection signals (a) and (b) which are in inverse proportion to the distances from the position of the center of gravity of the light quantity distribution of the image to the output terminals 18a and 18b. When the level of the sum signal (q) of the signals (a) and (b) is small, a multiplexer 54A connects an input terminal 0 and an output terminal OUT electrically. The difference signal (p) and sum signal (q) are amplified sufficiently before being inputted to a divider 42D because beta>>1, where betaq is the output of the variable gain amplifier 54. When the level of the sum signal is extremely large, an input terminal 3 and the output terminal OUT are connected electrically to each other. Therefore, the difference signal (p) and sum signal (q) are inputted to the divider 42D as they are because beta=1, where betaq is the output of the variable gain amplifier 54. Consequently, an accurate gravity center signal (d) is obtained.
